RICHARD H. GARDNER AND JOHN l'V. GARDNER, OF TROY, NEW YORK.

MACHINE FOR CURLING COLLARS AND CUFFS.

SPECIFICATION forming part of Letters Patent No. 242,295, dated May 31,1881,

Application filed April 52, 1860 (No model.)

To all whom it may concern:

Be it known that we, Brennan H. GARDNER and J. VVRIGH'L GARDNER, of thecity of Troy, county of Rensselaer, and State of New York, have jointlyin ven ted a new and useful Im provement in Machines forOurlingOollarsand Cuffs, of which the following is a specification.

Our invention relates to such devices as are constructed to curl up froma flat form apparel collars and cuffs after they have been laundered andironed, the object being to shape them so that they can be packaged in aform which is adapted to that part of the person to which they areapplied when worn.

Accompanying this specification, and forming a part of it, are threeplates of drawings, each plate containing one figure in illustration,Figure 1 showing, in perspective, a view of a cuff and collar curlingdevice containing our invention, taken so as to illustrate theconnections made at one of its ends for receiving and transmitting powerto actuate its co-operatin g parts. Fig. 2 illustrates a verticalsection of the same machine, taken at right angles to the engagingsurfaces of the two rollers, which, by their revolving contact, asarranged, curl up the articles passed between them. Fig. 3 illustratesanother view, in perspective, of the same machine, taken so as to showthe end of the latter which is opposite to that indicated in Fig. 1.

In all of the illustrations the same letter-references indicate the sameparts, and these are designated and described as follows:

At A there is shown an elastic roller, having its shaft-bearings in theframestandards L L, and as designated at S.

At A there is illustrated a non-elastic roller, made of metal, and ashaving its journals at S S in the adjustable boxes at d, with the latterconstructed so that they can be moved up or down between the standards PP by means of guide-flanges O O O O.

In thetop of them-aehine-frame, and connecting with the standards 1 P,are arranged the set-screw plates 00 00, attached at a a, and containing, by means ofa centrally-located threaded connection, the set-screws T'l, and so arranged that when the latter are screwed down in theirthreaded plates the points of the screws will engage with the boxes (1d, in which the bearings of the metallic roller are placed, and

thus force down the face of the latter against the yielding surface ofthe elastic roller, so as to produce at their point of contact a slightdepression in the face of the elastic roller, as shown at L, Fig. 2, andthis depression will be increased in depth by the intervening thicknessof the material being curled. To allow this vertical adjustment of thebearing of the metallic roller-shaft the gear-wheel from which itreceives motion axially fits loosely into the teeth of the one upon themetallic roller, so as to permit a slight vertical variation of theshaft of the latter without interfering with its geared connection, fromwhich actuating-power is derived. As the surfaces of the two rollersengage thus impressed, the depression produced in the exterior of theelastic roller will only continue at their point of revolving contact,for the elasticity of the material of which the latter roller is madewill cause its return in surface extension to conform to the usualcircumference of it, when the point of impressed contact in it is passedby the revolution of the rollers.

AtB there is shown a guide-roller, arranged to turn in mandrel-bearingsformed on the cranks b I), and the latter having journals andclutching-nuts on the machine-frame, atDD, by means of which theguide-roller is constructed to swing down when not used, as shown in theposition designated by the dotted line B. When used the guide-roller isplaced as designated at B, and the collars or culfs are fed into themachine over its top, as indicated at Y, by the passing cuff C O.

At S there is indicated the driving-shaft,

and which is provided with the gear-wheel F,

and upon which shaft there is attached a pulley, instead of thehand-crank a, when the machine is to be actuated by power. This gearedwheel F, by means of the intermediate pinion F and shaft 5", aot-uatesthe metallic roller-shaft S and the same driving-- shaft S, by means ofthe pinion E upon its end opposite the pulley, and as shown in Fig. 3,and the connecting geared wheel E actuates the roller-shaft S of theelastic roller A. The letter K is placed to indicate themachineplatform, and the letters L L to designate the vertical supportsof the device.

As the curling eifeet upon the material treated by the machine isproduced by the impressed contact made between the adjustable metallicroller and the elastic roller and their opposite axial revolution, theeffect will be the same whether one of these rollers actuated the otherby their impressed traction, or both had intermediately-arranged gearedconnection to actuate the rollers, as shown, and the effect of theimpressed contact will be the same, so far as the metallic roller andthe elastic roller are concerned, when actuated to revolve in oppositeaxial revolution, whether the impressed contact between the rollers isproduced by means of the set-screws or by weighting the ends of themetallic roller-shaft by means of rods and strapped bearings for itsjournals.

The elastic roller is provided with a metallic shaft and journals, andit may be made of rubber or other similar substance having suitableconditions of elasticity, and such as will allow it to yield enough uponits surface to form a slight indentation or depression where thenonelastic or metallic roller is forced down against its exterior, andwhich will by its elasticity return to its usual circumferential surfaceafter having passed the pressure contact.

While we have described the non-elastic roller as made of metal, we donot desire to limit our invention to the use of the latter material, forwood or any similar substance harder than rubber or the m aterialofwhich the elastic roller is made, and which by its impressed contactwill form a depression in the surface of the latter at the pointofcontact, will answer the same purpose.

We are well aware that an endless belt running upon two guide-rollersand underneath an intermediate roller has been employed to accomplishthe same purpose, by passing the articles to be curled between adepression formed in the belt and the intermediate roller. This devicediffers from ours in the fact that the curling depression we employ isproduced in the surface of an elastic roller by its inipressed contactwith a non-elastic roller, and no belt is employed.

Having thus described our invention, what we claim, and desire to secureby Letters Patent, is

1. In a machine for curling collars and cuffs having an elastic rollerand a non-elastic or metallic roller with their surfaces in an impressedcontact when revolving, the roller B, to bend or curve the collars orcuffs passing between the curling-rollers before entering between thelatter, as shown and described.

2. The combination, with the elastic roller A and non-elastic rollerA,ofthe guide-roller B, arranged to turn in mandrel-bearings formed oncranks and capable of being swung down when not in use, substantially asdescribed.

Signed at Troy, New York, this 30th day of March, A. D. 1880.
